A CORPORATION OF PENNSYLVANIA.

Specification of Letters Patent.

Patented July 28, 1914.

Application filed January 20, 1.913. Serial No. 743,027.

T all 211/1, (/77). it may concern llc it known that I, JOHN HAWLEY TAUssm, a citizen of the United States, residing at the city of Philadelphia, in the county ol? Philadelphia and State 0 Pennsylvania, have invented a certain new and useful Base llhlll f for Vertical Gas-Retorts, of which the following is a specification.

In the operation of vertical gas retorts leakage not. infrequently occurs past the doors which constitute the bottom closures of the retorts. This leakage results in the escape of gas which is of course wasteful. llloreovcr, the gas frequently becomes ignited and burns producing undue heating of the parts and positive injury t), if not destruction of, the apparatus or parts thereof.

iVlyinvention is based upon the e itist-once of sufiicicnt gas pressure inside the retorts and above the bottom doors for causing leakage at the doors although there may be practically no pressure at the tops of the retorts where the gas is usually led off by an exhauster.through a water seal. In accordance with my invention gas is led off not only from the tips but also from the bottoms of the rctoits so that there is not sull'icicnt gas pressure above the docrsior causing loaka e. i

The principal objects of my invcntimrarc to prevent leakage at the doors; to provide convenient and reliable apparatus for drawlfi f 0t? gas above the scaling portions of the doors; and to provide for cleaning the ducts by \if llitfll the gasfiis drawn and led oil.

lhc ji vcntion comprises the improve- Ififljltfilflbt) claimed at the cod hereof and to he first described. in connection with the accompanying drawings illustrating certain embodimentsof the invention chosen from other riabodi :nts'foi the sake of explanzv tion.

la the drawings Figure. .1, is an elevational view, g rtly in section, illustrating one cinbodiazcnt ot' the inventiim. Fig. 2 is a similar view drawn to an enlz-irged scale and illustrating details of construction. Fig. 3, is a scctioi-il view drawn to an enlarged scale and taken at right angles to the sec tion of vi 'i Fig, 4-, is a bottom plan view, and Fig. 5, is a sectional view illustrating a modification.

A base closure for vertical gas retorts cmbodying features of the invention comprises a door having two parts with accessible gas space between them and whereof one part operates as a seal and the other part as a charge support, in cooperation with a door frame provided with a gas off-take communicatingwith the accessible gas space.

In the drawings, Figs. 14, 1, is the accessible gas space, and in Fig. 5, 1, is the accessible gas space. In Figs. l4, the part 2, is the charge supporting cover, and the part 3, operates as a seal. In Fig. 5, the part 2, operates as a charge supporting cover, and the part 3 operates as a seal. In Figs. 1-4, the door frame 4, is provided with gas ofi takes 5 communicating with the space 1. In Fig, 5, the door frame 4, is provided with gas oil-takes 5", communicating with the space 1. As shown the gas elf-takes 5 and 5, are alincd so that they can be cleaned as by means of a tool inserted at 6.

7, is an cduction pipe (,omn'ulnicating with the gas ofl'-takes and with a hydraulic seal 8, from which gas is drawn as by means of an cxh auster 9, which discharges into suitable gas storage apparatus.

As shown in Figs. 14, the parts 2 and 3, are united as at 10, toward one side of the door and at the opposite sidethese parts are supported by a support 11. The area of the part 3, exceeds the area of the part 2, so that gas can. enter the space 1, from the interior otthc lower part of the vertical retort 12. This is the sense in which the space 1, is said to be accessible, meaning that. as can enter while the retort charge is supported above it. In these figures the bottom closure is supported by a cotter bar 13, pivoted at 14, and detachahly clamped at 15.

In Fig, 5, the parts 2 and 3, are pivoted at 16 and 17,and dctachably clamped at 18 and 19. The part 2", sustains the charge but permits gas to reach the accessible space 1.-

The door 3", seals the gas, and the gas is drawn oil atfi. 20, are gas eduction connections at the tops of the retorts, and 21, are portions of the same.

lo/ing two parts with accessible gas space het/ween and whereof one part operates as a "seal and the other as a charge sup-port, and

a door frame provided with a gas elf-take communicating with said space, substantially as described.

2. A base closure for vertical gas retorts comprising the combination of a door, a charge supporting cover applied near one edge of the face of the door with accessible between the cover and. door near the other edge of the latter, and means for drawing ofl gas from said space.

3. A base closure for vertical as retorts comprising the combination of a cor frame having door openings, alined gas ducts opening through the walls of the openings, doors adapted to seal the openings below the ducts, and charge supporting covers arranged above the ducts and adapted to permit of i the passage of gas thereto.

v 4. A base closure for vertical gas retorts comprising the combination of a door frame having door openings, gas ducts opening through the walls of the openings, doors adapted to seal the openings below the ducts, and charge supporting covers arranged above the ducts and adapted to permit of the passage of gas thereto.

5. A base closure for vertical gas retorts comprising the combination of a door frame provided with openings and with duets communicating with the openings, means for above the ducts past which gas may be drawn. to the ducts.
